A premium, agentic, non-blocking visual orchestrator designed to compose, compile, test, and package Spring WebFlux Java Microservices in real-time. Inspired by n8n and built on top of React Flow and Spring Boot, it bridges visual flow architectures directly to native Java structures.
- 🎨 Visual Microservice Composition: Drag, connect, and customize WebFlux controllers, handlers, facades, services, repositories, and entities.
- 📦 Dynamic Java Project Exporter: Generates complete Java maven packages directly onto the host filesystem, complete with
pom.xml,application.yml, and clean, ready-to-run code. - 🔄 Host Maven Dependency Caching: Integrates host volume mounts to sync and pre-download jar dependencies directly to
~/.m2using containerized Maven offline tasks. - 🚀 Live Integration Test Runner: Connects to external APIs (using reactive
WebClient) and runs full integration sequences in memory, outputting step-by-step console logs. - 📂 Portability: Import and export workflow configurations as standard JSON schema files.
We have seeded a complete end-to-end GET /api/posts/{id} data ingestion workflow. Below is a detailed walkthrough of each architectural node layer and its parameters:
Defines the Spring Boot starter parent and registers reactive dependencies (WebFlux, Lombok, MongoDB).
Specifies the HTTP path /api/posts/{id} and maps the GET operation to the PostHandler.
Extracts the route path variables and passes the incoming payload down to the Facade component.
Decouples request/response formatting from business logic by delegating variables to the service.
Executes the business logic, logs debug traces, triggers the HTTP client, and saves the entity to MongoDB.
Executes a live non-blocking HTTP GET call to retrieve the requested post resource.
Defines the POJO structure with Lombok annotations (@Data, @Builder, @NoArgsConstructor, @AllArgsConstructor) and maps to the target MongoDB collection.
Extends the Spring Data ReactiveMongoRepository interface to provide built-in CRUD operations.
Holds the database credentials and coordinates connectivity to MongoDB.
